通过国内外鱼道研究、应用资料以及现场调研，比较详细地介绍了国内外鱼道设施的建设、发展过程和鱼道结构所包含的主要类型；列出了国内外多个鱼道隔板型式和相应的水力特性；总结了鱼道设计的一般性原则；分析了国内外鱼道过鱼条件和适用情况的差异以及我国鱼道设计中存在的问题等。

Methods: A retrospective study was conducted using an insurance database from Bureau of Nation Health Insurance - Central regional branch with registered children born in 2001 who received teeth fluoridation and anti-decay program. The difference of utilization of dental care preventive service analysis was based on each individual child's character and required dental treatment. For cost-benefit analysis, children were selected who were eligible receiving or non- receiving this benefit from July 1, 2004 till 2007. Two groups were compared by frequency matching analysis, based on sex, medical provide territories, insured fee. Additional Incremental benefit/cost method of cost-benefit analysis is also conducted to evaluate the service providing cost increasing and dental treatment cost decreasing effectiveness.

研究方法主要系透过健保局中区分局93年至96年儿童牙科医疗费用统计资料，比较90年次出生之儿童接受涂氟预防保健服务之人口学特质及其涂氟前后牙科医疗利用差异；并依该等对象接受涂氟预防保健服务与否区分两组，就其性别、就医地区别与全民健保投保金额组别等予以配对，进一步应用成本效益分析（cost-benefit analysis，CBA）之增量益本比（Incremental benefit/cost method，IBC），探讨儿童牙齿涂氟预防保健服务成本的增加，使牙科医疗费用减少所带来效益的增加为何。
